Suppose that you have a message consisting of 1024 bits. design a method that will extend a key that is 64 bits long into a string of 1024 bits, so that the resulting 1024 bits can be xored with the message, just like a one-time pad. is the resulting cipher as secure as a one-time pad? is it possible for any such cipher to be as secure as a one-time pad? 21. design
